Abstract
Primjena dubinskih klipnih sisaljki s klipnim šipkama najstariji je i najčešće korišten sustav za prinudno podizanje kapljevine. Način rada sustava podrazumijeva prijenos energije i pogona od pogonskog motora na površini do niza klipnih šipki i dalje do dubinske klipne sisaljke. Podizanje fluida postiže se cikličnim kretanjem klipa prema gore i prema dolje. Tijekom rada u bušotini, dubinska oprema izložena je različitim tipovima opterećenja, i vibracijama, uz druge bitne elemente kao što su utjecaj tlaka i temperature te korozivnosti ležišnog fluida. Posljedično, nastaju značajna oštećenja i kvarovi povezani uglavnom s nizovima klipnih šipki i uzlaznih cijevi. Najčešće prisutni kvarovi su mehaničko trošenje spojnica klipnih šipki i propuštanje uzlaznih cijevi. Ostali primjetni kvarovi odnose se na dubinsku klipnu sisaljku i uključuju čepljenje sisaljke, propuštanje mirujućeg i putujućeg ventila te ispadanje klipa iz cilindra. Ovaj će rad donijeti pregled mogućih kvarova dubinske opreme u eksploatacijskim bušotinama koje su opremljene dubinskim sisaljkama s klipnim šipkama. Definirat će uzroke spomenutih kvarova uz rješenja i metode korištene s ciljem smanjenja njihove učestalosti. Nakon teorijskog objašnjenja, prikazat će oštećenja dubinske opreme na primjeru jednog hrvatskog naftnog polja.
Abstract (english)
Sucker rod pumping is the oldest and most utilized artificial lifting system. The working principle of a system implies energy and power transportation from a surface power source to the sucker rod string and then to the sucker rod pump. Fluid lifting is achieved by a cyclic upward and downward movement of a plunger. During its stay in a well, downhole equipment is exposed to different types of load and vibrations along with other important elements like pressure and temperature influence or corrosiveness of a reservoir fluid. As a consequence, significant damages and failures occur, connected mostly with rod and tubing strings. The most frequent failures are rod string couplings mechanical wear and tubing leakage. The other notable failures refer to the sucker rod pump and include pump plugging, standing and travelling valve leakage and plunger dropping out of the cylinder. This thesis will present a review of potential downhole equipment failures in production wells equipped with a sucker rod pumping system. It will also define causes of the mentioned failures along with solutions and methods being utilized to reduce the frequency of their occurence . After theoretical explanation, an example of one Croatian oil field with downhole equipment failures will be given.
